How well can computers connect symptoms to diseases?

A new MIT study finds “health knowledge graphs,” which show relationships between symptoms and diseases and are intended to help with clinical diagnosis, can fall short for certain conditions and patient populations. The results also suggest ways to boost their performance. Health knowledge graphs have typically been compiled manually by …

How to verify that quantum chips are computing correctly

In a step toward practical quantum computing, researchers from MIT, Google, and elsewhere have designed a system that can verify when quantum chips have accurately performed complex computations that classical computers can’t. Quantum chips perform computations using quantum bits, called “qubits,” that can represent the two states corresponding to classic …

Tool predicts how fast code will run on a chip

MIT researchers have invented a machine-learning tool that predicts how fast computer chips will execute code from various applications.   To get code to run as fast as possible, developers and compilers — programs that translate programming language into machine-readable code — typically use performance models that run the code through …
